Afraid of Help

Is it hard for technology workers to ask for help? Or accept it? We seem to often be the type of people that want to solve problems and fix things on our own. Is that a problem? Steve Jones thinks that we should sometimes put aside our pride and get things done.

Sparse Columns – ConvertSVtoXML & XMLToResv

Not very often I run across something with zero matches in a search engine, but had it happen recently. I had set up a simple demo of a sparse column set and happened to look at the execution plan, was interested to see that the Compute Scalar was backed by ConvertSVtoXML. This was on a select from a table with one row, and then, being a little more curious, updated it with an xml fragment I saw a call to ConvertXMLtoResv. I’d venture that those serve to convert back/forth from XML storage.
